Specification of Letters Patent.

Patented A 14,11 111,

To all whom it may concern:

Be it known that I, RAY E. DURHAM, a

citizen of the United States, resident of Cleveland, county of Ouyahoga, and State of Ohio,ihave invented a new and useful Improvement in Land-Rollers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to land rollers, and

particularly to land rollers in which there;

is employed a loosely mounte suitable frame.

The object of the invention is to provide ang of hollow roller wheels 5 upon'an axle carried by a a construction whereby the end disks of the land roller may be readily removed so as to permit of'the formation of a central open space whereby rows of the growing grain may be avoided while the soilbetween the rows is being cultivated or pulverized.

Thesaid invention consists of means hereinafter fully described and particularly set forth in the claims. p The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the inventionmay be employed.

In said annexed drawings:-

Figurel represents a perspective view of a land roller or pulverizer embodying my invention.

Fig. 2' represents a view similar to Fig. 1, showing the two end rollers removed and the intermediate space formed.

Fig. 3 represents a vertical vaicial section of one of the end disks.

Fig. 4 re resents a side elevation of such end disk, s owing the two parts separated from each other. I

Fig. 5 represents an elevation, taken from the opposite side from. that shown inFig. 4, of such end disk and showing the two parts connected.

Fig. 6 represents a view similar to Fig. .5 showing the other side of the disk.

Fig. Trepresents a section'of a detail ortion of one of said end disks, taken upon ine VIIWVII, Fig. 6.

The illustrated embodiment of my invenimmediately gether form bearings for the reception "of p 4. hi arr n m n !be n rro iil to conserve materialand rendertl 'estructure as l ght as possible. When the two disk tive parts andiadjacenti toI the: innerisur ace of the webs 11 of the other part, ,as sh in f Fig. .6. ,The inner side of, eacl ,ofitliese: lugs securely in Place by. m an tita gin' "17 vided with end frames 2, 2 and having so: cure thereto an ordinary tongue 3 WhlCll is mounted the seats. The'end or side frames 2 each carries a bearing a in which is mounted, either rotatably or fixed, 6 0- the axle 6. Upon this 7 axle are loosely mounted a multiplicity of roller or pulverzer disks 7, as will be readily understood.-

Instead, however, of forming all of these disks exactly alike, as has heretofore been .65 the custom, the end disks'S, 8, and the disks f adjacent thereto. namely disks 9, 9,are-modified instructure. The-extreme or end disks 8 are each formedof twoarts se arable upon a jl an'e 10 passing throug the isks axis, as is own U in Figs. 3 and 4. Each of these parts is ,ht il low and is formed with two side webs 10. and 11. Each of thesewebs is'formed with ,a semi-circular bearing12 and E13respecti" l which when the parts are assembled,

The'two center disks 9, 9, may also be constructed so as to have their opposing faces imperforate, as shown, so that their construction will'be exactly similar to that of disks 9, 9, with one side wall spokedand the other lmperforatei' It will thus be seen that by means of theabove-described structure,the desired interthe end disks 8, and that also the ends of mediate or middle space may be readily formed by reason of'the ready removal of the gang, under both sets of conditions above-mentioned, are closed to the ingress of dirt into the interior. 1
